Hydroxypropyl methylcellulose and gum arabic composite edible coatings amended with geraniol to control postharvest brown rot and maintain quality of cold-stored plums
In this study, the effect of hydroxypropyl methylcellulose (HPMC) and gum Arabic (GA) edible coatings amended with 0.2% geraniol (GE) were evaluated for the control of brown rot, caused by Monilinia fructicola, on artificially inoculated plums (Prunus salicina Lindl., cv.

| description | In this study, the effect of hydroxypropyl methylcellulose (HPMC) and gum Arabic (GA)
edible coatings amended with 0.2% geraniol (GE) were evaluated for the control of brown rot,
caused by Monilinia fructicola, on artificially inoculated plums (Prunus salicina Lindl., cv.
Angeleno) stored for 5 weeks at 1 °C. Brown rot is the most important pre- and postharvest
fungal disease of stone fruits, causing severe economic losses worldwide. Geraniol is an
important constituent of many essential oils that can be obtained as a byproduct from different
industrial procedures, such as those of the juice industry. Fruit postharvest quality was also
evaluated after 5 and 8 weeks of storage at 1 °C, followed by 3 days at 7 °C plus 5 days at 20
°C, simulating packinghouse, transport, and retail shelf-life conditions, respectively. HPMC
coatings containing 0.2% GE reduced the incidence and severity of brown rot by 37.5 and
64.8%, respectively, compared to uncoated fruit after 5 weeks of storage at 1 °C. HPMC-coated
plums, with and without GE, showed the highest level of firmness, the lowest change in
external peel color parameters (L*, a*, b*, C*, hue), and the lowest flesh bleeding compared
to uncoated control and GA-coated samples throughout the entire storage period, which
correlated with a higher gas barrier of these coatings without negatively affecting sensory
quality. Furthermore, the HPMC-0.2% GE coating provided the highest gloss to coated plums,
showing the potential of this coating as a safe and environmentally friendly alternative to
conventional fungicides and waxes for brown rot control and quality maintenance of coldstored
plums |
